1 Claim.

Our invention provides an extremely simple and highly efficientfrictional window sash holder, and is designed to be substituted forother well known, relatively expensive, and cumbersome apparatus such asis used in the weight and pulley system. It is adapted to be readily andeconomically installed on old as well as new windows. A furtherdesirable feature of the device is that it holds the window undersufficient tension or friction to keep tight joints and preventrattling.

Generally stated, the invention consists of the novel devices andcombinations of devices hereinafter described and defined in the claim.

In the accompanying drawing, which illustrates the invention, likecharacters indicate like parts throughout the several views.

Referring to the drawing:

Fig. l is an inside front elevation, some parts being shown in section;

Fig. 2 is a sectional view taken on the line 2 2 of Fig. 1;

Fig. 3 is a perspective of the device, some parts being omitted;

Fig. 4 is a cross-sectional view taken on the line 4-4 of Fig. 2; and

Fig. 5 is a side elevation showing the shoe of the holder removed fromthe cylinder or barrellike casing thereof.

The numeral 6 indicates a Window frame which may be a narrow structureand need not include the box arrangement inasmuch as weights, cords andpulleys will not be employed. The upper and lower sash of thedouble-hung window are indicated by the numeral 7. The inside stop stripis indicated by the numeral 8 and the parting strip by the numeral 9,the outside stop strip not being shown but may be of the usualconstruction.

In accordance with an important feature of the invention the frictionalsash holders hereinafter described are applied to each sash in a threepoint arrangement, two thereof being applied to one side of the sash andthe third at the opposite side of the sash on a horizontal line midwaybetween the two first noted holders. As preferably constructed and shownin the drawing, each sash holder comprises a cylinder or barrellikecasing 10 that is countersunk into a bore formed in the outer edge ofthe side rails of the sash. The casing 10 is closed at its inner end andat its outer end has a slightly outturned stop flange 11 that is flushwith the outer edges of the sash. The inner end of the casing 10 isclosed and an adjusting screw 12 works with threaded This screw 12 ispassed through a relatively small bore in the sash and its extended endis exposed or positioned so that a slot 13 in the end thereof may bereadily engaged by a screw-driver or the like. The shoe 14 of the holderis a disc-like structure with rounded or slightly backturned edge and isprovided with a sleeve l5 of reduced diameter that fits telescopicallyinto the casing 10. This sleeve 15 is provided with a bayonet slot 16that is engaged by a pin 17 applied to the interior of the l casing 10 ashort distance inward from its outer end.

A washer-like spring cap 18 is applied to the reduced inner end of thescrew 12 and is formed with an axial pocket that receives the reducedend of said screw. A coiled spring 19 is compressed between the springcap 18 and the shoe 14 into the sleeve 15 of which its outer end isprojected. Obviously, the tension of the spring 19 may be varied byadjustments of the screw 12 and without removing the sash.

Under the tension of their springs 19 the shoes of the several fastenerswill be frictionally pressed against the frame. The said springs shouldbe so adjusted that each sash will be supported by its threefrictionally-acting spring-pressed shoes. This three point contact willprevent rattling of the sash and provides an arrangement in which thefriction holding the sashwill be applied nearly or entirely to the shoesrather than between the sash and the window frame.

It is highly important to note that when the pin or projection 17 isengaged with the longitudinally extended inner extremity of the bayonetslot 16 and the sash is in position, it will not be possible for theshoe to move far enough to align the said pin with the elbow or entranceportion of said slot, and hence, will be impossible for said pin to getinto the entrance passage of the said slot. Even when the sash isremoved the pin will be locked in the inner extremity or longitudinallyextended portion of the bayonet slot. Removal of the shoe from thecasing, when the sash is removed, will require the shoe to be forcedinward just far enough to bring the elbow portion of the slot 16 intoalignment with said pin. The spring cap 18 holds the engaged end of thespring against lateral displacement and the sleeve 15, of course, holdsthe outer end of said spring properly positioned. 'Ihe springs of theseveral holders should be so adjusted that there will be just the properfriction required to hold the sash against accidental downward slidingmovement.

From the foregoing it will be understood that adapted to be set into asash, a spring-pressed follower telescoped into said casing and havingan exposed shoe at its outer end, said tubular casing having an inwardlyprojecting lug and said shoe being provided with a bayonet slot in whichsaid lug is engageable, the longitudinal locking slot of said bayonetslot being connected in its medial portion to lan L-shaped release slot.
